1.1. Intel® FPGA PTC Power Model Status

The Main page of the Intel® FPGA Power and Thermal Calculator (PTC) shows the current power model status for the selected device. The power models in the Intel® FPGA PTC can be in advance, preliminary, or final status:
  • Advance power models are based on simulation results, process model projections, and design targets. Advance power models may change over time.
  • Preliminary power models include post-layout simulation results, process data, and initial silicon correlation results. Preliminary power models may change over time.
  • Final power models correlate to production devices with thousands of designs, and are not expected to change.
The accuracy of the power model is determined on a per-power-rail basis for both the Intel® Quartus® Prime Power Analyzer and the Intel® FPGA Power and Thermal Calculator. For most designs, the Power Analyzer and the Intel® FPGA PTC have the following accuracies, assuming final power models:
  • Intel® Quartus® Prime Power Analyzer: Within 10% of silicon for the majority of power rails and the highest power rails, assuming accurate inputs and toggle rates.
  • Intel® FPGA Power and Thermal Calculator: Within 15% of silicon for the majority of power rails and the highest power rails, assuming accurate inputs and toggle rates.
